OK....... Hawke Compact 4-16x44 fitted on my now tamed HW95k, first day out to zero it and continue pellet testing only to find I've run out of vertical adjustment by quite a large amount!

With elevation turret adjusted to its limit point of impact is about 2" below point of aim at 25yds - shimming rear has been suggested, but its not something I've ever had to do before, and honestly a bit wary about how it could effect tube of scope with a mismatch between front and rear, wouldn't take much to mark or twist tube

Sportsmatch mounts seem to be out of stock everywhere, and only other I can find are the FX no limits mounts

Any clever solutions?
